CHARLES G. WRIGHT, F 'AMIBLER, PENNSYLVANIA,

srArLE-ExrnAcTon.

' To all whom it may concern Be it known that 1, CHAR ES WnIGH'r, a citizen of the United States, residingzat Ambler, in the county of Montgomery, State.

of Pennsylvania, have invented a new and useful Staple-Extractor, of which the following'is a specification.

My invention consists of-a tooladapted to,

extract a staple in a convenient, easily operposite sides of a staple extractor embodying my invention. v

v ig. 3 represents a side elevation of the extractor at a right angle to Figs. 1 and 2 1n inclined position preparatory to engagement.

with a staple.

Fig. 4 represents a bottom plan View thereof.

Fig. 5 represents a transverse section of the foot of the extractor on line 55 Fig. 3.

Fig. 6 represents atransverse section thereof on line 6-6 Fig. 3.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings.

1 designates a shank forming the handle 'of the tool, and 2 designates a foot which extends at n angle from the shank at the lower end of the latter.

The foot extends tapering from theshank toits terminal forming the single point 3,

and has all of its sides fiat as at 4- 1, 55,

the corners of the foot-thus being angular.

The sides of the foot adjacent to the place of junction with the shank are tapered or sloped inwardly in down direction as at 6, forming the heel 7 of the tool of reduced width and with angular corners on its bottom, the under surface of said bottom being curved from front torear.

What may be termed the back of the foot has thereon the flat surface 8 which is somewhat in a right line from the point 3 of the foot so as to receive the impact of a hammer Specification of Letters Patent.

or the like to drive the said point under the v crown of the staple.

The operation is as follows The tool is placed at an inclination-on the post, board, etc. in which a staple is secured adjacent to the crown of the latter and the point 3 directed to the underside of said crown, the underside 4 of the foot resting solidly on said post. j

The flat face 8 of the back of the foot is then subjected to the blows of a hammer or crown of the staple and raises it to great extent causing the legs of the latter to be extracted from the post, the leverage of the shank and foot with the assistance of the other features of the foot causing the exoperated and powerful manner.

As the foot rests on the wood in which the staple is contained, the tool may be levered on the wood by the curved heel to raise the foot and consequently lift the staple, the narrow under face of the heel is adapted to bite into the wood so as to take firm hold thereof while the foot presses upwardly against the underside of the crown of the staple between the. tops of the legs thereof, thus starting the staple and finally. raising it. In cases where the staple legs are rusted inthe wood and'so held with greater tightness the tool may be rocked laterally on. its narrow heel and the slopes on the sides of the foot andso the staple may be worked out from side to side of the wood. These slopes leave the top of the anglewhere the footjoins the shank of the full material of the tool thereat thus preserving the strength of the tool at said angle where the same is needed owing to the great strain occasioned there in working the tool in the various directions up and down and to the right and left, avoiding twisting of the foot on the shank, and vice versa.

The heel of the foot being narrow causesthe heel to bite thepost, and by its angles at I traction of the staple in a convenient, easily- .ters Patent, is

As an improved article of manufacture,a

its lower corners to take firm hold-thereof preventing sideslipping of theheel on said post.

The flat sunface of the back of the foot'is positioned in relation to the point of the-latter as to indicate the proper place where the blows of a hammerare to be made so that said point is properly directed to the place of application under the crown of the staple.

Having thus described my invention, What I claim as new and desire to secure by Letstaple extractor, the same being constructed of a shank and a foot, the latter of angular form in cross section tapering from" said shank to a single point, said foot having on 7 its underside at the rear thereof a curved heel, a hammering surface at the top of the rear of the latter, and slopes on its sides exterial of the tool at the top of the angle of the shank andfoot.
